T-Mobile polled customers and found that 40% of you worry about going over your monthly data allowance. In an effort to solve that problem, and draw attention away from rivals recent aggressive moves, the company has rolled out cheaper unlimited plans. And unlike Sprint’s new “half price” offer that in many ways is less than meets the eye, T-Mobile’s deal is pretty straightforward: $100 a month gets you 2 lines of unlimited data, voice and texting. For each additional line up to a total of 10, you’ll pay $40 apiece. For lighter users, the company also resurrected a plan that costs $100 for 4 lines, giving each 2.5GB through the end of next year. The plan then reverts to 1GB per user. But unlike with other carriers, T-Mobile merely slows your service when you hit your cap rather than charging you extra. With high-end and low-end offers, the usual questions remain: Should you jump at the new deals?
Unlimited sounds great, why wouldn’t I want this?
There are probably two main reasons why this deal wouldn’t appeal to you. First, T-Mobile’s service is often less than spectacular, especially outside of urban areas. If you live and travel in areas in where T-Mobile has good, reliable coverage this reason won’t turn you off. Otherwise, it might end the conversation before it starts. Second, most people simply don’t need this much data. Average usage is typically below 2GB per user each month. Right now, Sprint will give you 20GB to share for up to 10 lines (after Dec. 2015 the price will go up). That 20GB will cover all but the most data-hungry users, especially because the pool is shared. In a month where you use less, someone else in your family can use more. That tends to balance out.
